Project vs Program vs Portfolio

A project is a temporary endeavor that produces a unique output, such as a deliverable or capability. A program groups related projects—and often ongoing work—managed together to realize benefits unattainable by managing each project independently. A portfolio encompasses programs, projects, and operations aligned to strategic objectives, balancing resources and priorities across the investment mix. The exam distinction is focus: project managers deliver scope on schedule and budget; program managers optimize interdependencies and harvest benefits; portfolio managers ensure the organization invests in the right work. Beware questions conflating program management with mere multi-project coordination—a program must deliver a shared benefit transcending individual project outputs.
